Question

Two lenses, one converging the other diverging, each have a focal length of 16.5 cm. They both produce virtual images 30 cm from the object. Determine the location of the object and image for each lens and the corresponding magnifications.

Answer #1

Two lenses, one converging with focal length 20.0 cm and one
diverging with focal length -11.7 cm , are placed 25.0 cm apart. An
object is placed 60.0 cm in front of the converging lens.
Determine the position of the final image formed.
Express your answer with the appropriate units.
di =
Determine the magnification of the final image formed.

A diverging lens with a focal length of -19.7 cm and a
converging lens with a focal length of 11.0 cm have a
common central axis. Their separation is 39.5 cm. An
object of height 1.1 cm is 26.4 cm in front of
the diverging lens, on the common central axis. Find the location
of the final image produced by the combination of the two
lenses.
Where is the image located as measured from the converging
lens?

Two lenses, one converging with focal length 20.5 cm and one
diverging with focal length ? 10.5 cm , are placed 25.0?cm apart.
An object is placed 60.0?cm in front of the converging lens.
Part A Find the final image distance from second lens. Follow
the sign conventions. Express your answer to two significant
figures and include the appropriate units. di2 = Part B Determine
the magnification of the final image formed. Follow the sign
conventions. Express your answer using...

The focal lengths of the converging and diverging lenses are +15
and -20 cm, respectively. The distance between them is 50 cm and
the object is placed 10 cm to the left of the converging lens.
Determine the location of the final image with respect to the
diverging lens. Is this image real or virtual? Find the total
magnification; is the image inverse or upright?

A diverging lens with a focal length of -11.3 cm and a
converging lens with a focal length of 14.6 cm have a common
central axis. Their separation is 30.9 cm. An object of height 1.0
cm is 33.1 cm in front of the diverging lens, on the common central
axis. Find the location of the final image produced by the
combination of the two lenses.
Where is the image located as measured from the converging
lens?

A diverging lens with a focal length of -15 cm and a converging
lens with a focal length of 15 cm have a common central axis. Their
separation is 12 cm. An object of height 1.0 cm is 10 cm in front
of the diverging lens, on the common central axis.
(a) Where does the lens combination produce the final image of
the object (the one produced by the second, converging lens)?
in cm
(b) What is the height of...

Two thin lenses with a focal length of magnitude 10.0 cm , the
first diverging and the second converging, are located 7.50 cm
apart. An object 3.00 mm tall is placed 16.7 cm to the left of the
first (diverging) lens.
How far from this first lens is the final image formed?
Is the final image real or virtual?
What is the height of the final image?
Is it upright or inverted?
Thank you!!

Two thin lenses with a focal length of magnitude 11.5 cm, the
first diverging and the second converging, are located 8.62 cm
apart. An object 1.90 mm tall is placed 19.2 cm to the left of the
first (diverging) lens.
A. How far from the first lens is the final image formed?
B. Is the final image virtual or real?
C. What is the height of the final image?
D. Is it upright or inverted?

Two thin lenses with a focal length of magnitude 11.0 cm, the
first diverging and the second converging, are located 8.25 cm
apart. An object 1.60 mm tall is placed 18.3 cm to the left of the
first (diverging) lens. Part A How far from this
first lens is the final image formed? Part B Is
the final image real or virtual? Part C What is
the height of the final image? Part D Is it
upright or inverted?
